COUYPLING DEVICE.

SPECIFICATION forming part of Letters Patent N o. 704,545, dated July15, 1902.

Application filed August 29, 1901. Serial No. 73,718. (No model.)

To ctZZ whom it may concern:

Be it known that LJoHN Gnoncn KANoUsn, a citizen of the UnitedStates,residing at Madi-V son, in the county of Dane and State ofWisconsin, have invented a new and useful Coupling Device, of which thefollowing is a specification.

This invention relates to a coupling device; and the object thereof isto provide a device of this character especially adapted for couplingthe handle of a pump or the operatingrod of a wind-engine to thepiston-rod of a pump.

More particularly, the object of the invention is to provide a couplingdevice in the form of an attachment which may be readily applied to anyordinary pump or wind-engine and when so applied is securely heldagainst accidental displacement both in operative andV inoperativeposition.

In order that a complete understanding of the invention may be acquired,the preferred form of construction is fully described in the followingspecification, taken in connection with the drawings which accompany andform a part of the same; but it will be understood that the constructionthus shown and de scribed is open 'to change and modification within thescope of the claims hereto appended.

In the drawings, Figure 1 is a perspective view of the preferred form ofconstruction. Fig. 2 is a horizontal sectional view lof the same. Fig. 3is a view similar to Fig. 2, but showing portions in elevation and thecoupling-pin in retracted position. Fig. Li is a vertical detailsectional View on the line X X of Fig. 3, more clearly illustrating therelation and operation of the locking-dog.

Similar characters of reference designate corresponding parts in all thefigures of the drawings.

In carrying out the invention according to the construction shown aframe 10 is provided, which is in the shape of a yoke comprising a pairof substantially parallel arms 11 and 12, connected at one end by thecross-bar 13.

The arm 11 is somewhat longer than the arm 12 and is provided with anopening 14 intermediate its ends, in which is slidably mounted acoupling-pin 15, that projects into the space between the two arms. Theend of the arm 11 is provided with an enlarged head 16, the outer sideedge of which is bifurcated to receive a lever 17, pivoted therein, oneend of this leverbeing connected to the outer end of the coupling-pin 15and the other end being formed into a handle, by means of which the pin15 may be slid back and forth, as will be readily understood. In order,however, to normally hold the pin 15 in operative position,the`head 16has a transverse socket 18, in which is seated a coiled spring 19, thatbears against the under side of the outer arm of the lever, being heldin place thereon by a stud 20, around which the end of the coiled springis placed. In order, however, to hold the pin 15 in retracted positionwhen so desired, a gravity-dog 2l is pivoted upon the upper face of thehead 16 contiguous to the inner end edge of the same. This dog has anenlarged upper portion 22, the outer face of which is inclined,'as shownat 23, and is adapted to drop behind. the inner arm of the lever when itis in an outer position, as clearly shown in Fig. 3.

The end of the arm 12 is provided with an angular extension 24, having asocket 25, the mouth of which is directly opposite the opening 14 of thearm11. In this socket is slidably mounted a locking-bolt 26, thatprojects into the space between the arms 11 and 12 and normally abutsagainst the end of the coupling-pinl, being yieldingly held in thisposition by means of acoiled spring 27, which is housed within thesocket 25 and bears against the rear end of the bolt. The projecting endof the bolt 26 is cut away to form an annular shoulder 28.

The application'of the device will be readily seen. The coupling-pin 15is retracted and the bolt 26 is forced back, after which the yoke isplaced over the bifurcated end of the pump handle A, wind engine pitman,or other device, to which it is to be applied. I/Vhen the bolt alineswith the opening, it will be forced into the same by means of the spring27; but this movement will belimited by the shoulder 28. Likewise, whenVthe'couplingpin alines with the opposite opening it will be urged intothe same by the spring 19, and thus the device will be securely lockedin place. At the same time the dog will hold the coupling pin inretracted position, as

IOO

shown in Fig. 3, thus leaving the bifurcation open for the readyinsertion oi' the piston-rod B or other device to be coupled thereto.When it is desired to couple the two together, it is only necessary toaline the opening of the piston-rod B with that of the handle A, raisethe dog 21, and thus allow the couplingpin to pass through the alinedopenings, as shown in Fig. 2.

When it is desired to disconnect the elements, it is only necessary towithdraw the bolt until the dog 21 drops behind the lever. This willleave the piston-rod entirely disconnected, but the coupling device willstill be locked securely upon the handle or pitman ready to be againthrown into immediate operative position. In practice Where a windengineand pump is employed a pair of these devices will be used, one upon thepitman and the other upon the pump-handle, although but one isabsolutely necessary, and should the pump piston-rod be provided withthe bifurcated end but one will be employed. By this means it will beobserved that a coupling device is. provided which is in the form of anattachment that can be applied to any ordinarypump or wind-engine and bymeans of which the operating elements may be connected or disconnectedeasily and quickly. At the same time the attachment is always lockedsecurely in place against accidental displacement.

While the invention has been described throughout in connection with thepump, it will be seen that it may be used for connecting variouselements together, and it is to be understood that it is not to belimited for use in connection with a pump or Wind-engine.

From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described invention will be apparent tothose skilled in the art without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction may be resorted to withou-t departing fromthe spirit or sacrificing any of the advantages of the invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination with a pair of elements to be coupled, said elementsbeing disposed in overlapping relation, of a coupler comprising a frameseparate from the elements and a locking device movably mounted upon theframe and engaging the overlapping portions of both elements to securethem together, said device being movable out of engagement with one ofthe elements but remaining in engagement with the other and constitutingmeans for securing the coupler upon said latter element.

2. The combination with a pair of elements to be coupled, said elementsbeing disposed .inoverlapping relation, of a coupling com-l prising ayoke that embraces both elements, and a coupling-pin slidably mountedupon the yoke and detachably engaging the overlapping portions of bothelements to couple the same, said coupling-pin being movable out ofengagement with one of the elements but remaining in engagement with theother and constituting means for securing the coupler upon said latterelement.
